| 摘 要： | 对宽板纯弯曲问题进行了分析，给出了应变中性层和应力中性层的表示式，用数值方法计算得到了应力中性层和应变中性层的关系。指出了虽然应力中性层和应变中性层都是内移的，但应力中性层的内移量小于应变中性层，并证明了这一结果适用于更一般的情况。

| Abstract: | The formula to calculate neutral surfaces of strain and stress are given by analyzing the wide plate bending process. The relationship between the two neutral surfaces is obtained based on numerical method. It is proposed that the variation of stress is smaller than that of strain after bending process even if the two neutral surfaces are all changed inward. This conclusion can be gotten in general situation such as conventional model of materials. |
